xfs: reshuffle dir2 headers

2011-07-13T11:43:48+00:00

Replace the current mess of dir2 headers with just three that have a clear
purpose:

 - xfs_dir2_format.h for all format definitions, including the inline helpers
   to access our variable size structures
 - xfs_dir2_priv.h for all prototypes that are internal to the dir2 code
   and not needed by anything outside of the directory code.  For this
   purpose xfs_da_btree.c, and phase6.c in xfs_repair are considered part
   of the directory code.
 - xfs_dir2.h for the public interface to the directory code

In addition to the reshuffle I have also update the comments to not only
match the new file structure, but also to describe the directory format
better.

xfs: byteswap constants instead of variables

2011-07-08T12:36:05+00:00

Micro-optimize various comparisms by always byteswapping the constant
instead of the variable, which allows to do the swap at compile instead
of runtime.

xfs: avoid usage of struct xfs_dir2_data

2011-07-08T12:35:38+00:00

In most places we can simply pass around and use the struct xfs_dir2_data_hdr,
which is the first and most important member of struct xfs_dir2_data instead
of the full structure.

xfs: kill struct xfs_dir2_block

2011-07-08T12:35:32+00:00

Remove the confusing xfs_dir2_block structure.  It is supposed to describe
an XFS dir2 block format btree block, but due to the variable sized nature
of almost all elements in it it can't actuall do anything close to that
job.  In addition to accessing the fixed offset header structure it was
only used to get a pointer to the first dir or unused entry after it,
which can be trivially replaced by pointer arithmetics on the header
pointer.  For most users that is actually more natural anyway, as they
don't use a typed pointer but rather a character pointer for further
arithmetics.

xfs: kill struct xfs_dir2_sf

2011-07-08T12:35:13+00:00

The list field of it is never cactually used, so all uses can simply be
replaced with the xfs_dir2_sf_hdr_t type that it has as first member.

xfs: cleanup shortform directory inode number handling

2011-07-08T12:35:03+00:00

Refactor the shortform directory helpers that deal with the 32-bit vs
64-bit wide inode numbers into more sensible helpers, and kill the
xfs_intino_t typedef that is now superflous.
